Aerodynamics Matter !!
Hello All. First post here... wanted to share some data on aerodynamics. I am designing an ultralight (under 100 lbs/ft) small travel trailer and wanted to find out the effect of shape on aerodyna...

Being so far in front of the trailer's front would likely cause a lot of turbulence behind the deflector due to the deflected air being sucked back down to the fill the "partial vacuum" that was created by the deflector forcing the air up and away. Separating air creates a high pressure/low pressure scenario. Think of it like what causes an airplane wing to lift/suck the plane up off the ground or the curve shaped sail on a sailboat to suck the vessel thru the water.
The low pressure area created by parting the air "which is a partial vacuum" pulls hard to relieve the lacking air in it. This suction is very powerful as can be witnessed by opening a vacuum packed can of coffee or other items. Airplanes are not pushed off the ground and sailboats are not pushed along, they are sucked to lift or move by lowered air pressure sucking toward high pressure. Weather and storms have the same effect. Think weather fronts, hurricanes, tornados, etc and how powerful they are and they usually have the added factor of temperature differences in play too.
